Description

Technical Field

[0001] This invention belongs to the field of flexible cable production technology, specifically relating to a production equipment for continuous stranding and tension synchronous control of flexible cable core wires. Background Technology

[0002] Existing production equipment for continuous stranding and tension synchronization control of flexible cable cores typically includes core structures such as a frame, tensioner, strander, winch, conduit, and drive components. Its working principle is mainly to adjust the tension of the cores through the tensioner, achieve continuous stranding of multiple cores with the help of the strander, and then complete the winding of the stranded cores through the winch. The conduit is used to guide and transport the cores to ensure that the cores do not deviate or wear during the stranding process. The synchronous pulley works in conjunction to achieve coordinated operation of tension adjustment, core transport, and stranding, which can basically meet the continuous production needs of flexible cable cores.

[0003] However, in actual production applications, the problem of insufficient equipment operation safety is particularly prominent, which seriously restricts the improvement of production efficiency and also poses potential hazards to the personal safety of operators.

[0004] Specifically, during the stranding process of flexible cable cores, the stranding area of ​​the strander and the winch is in a high-speed operating state, and this area usually lacks an effective protective structure. When operators are inspecting, debugging or handling abnormalities during equipment operation, hair, clothing and other items can easily be caught in the high-speed rotating stranding area, which can lead to safety accidents, causing personal injury and production interruption. Summary of the Invention

[0005] The purpose of this invention is to provide a production equipment for continuous stranding and tension synchronization control of flexible cable core wires. It aims to solve the problem that during the stranding process of flexible cable core wires, the stranding area of ​​the strander and winch is in a high-speed operating state, and this area usually lacks an effective protective structure. When operators are inspecting, debugging or handling abnormalities during equipment operation, hair, clothing and other items can easily be caught in the high-speed rotating stranding area, which can lead to safety accidents, personal injury and production interruption.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a production equipment for continuous stranding and tension synchronization control of flexible cable core wires, comprising a frame, a tensioner mounted on the surface of one end of the frame, a bearing seat provided on one side of the tensioner, a strander provided on one side of the bearing seat, a conduit installed through the interior of the bearing seat and the strander, a synchronous pulley mounted on the outer wall of the conduit near the end of the tensioner, and a drive mechanism installed between the bearing seat and the strander; One end of the winch is connected to a bearing on the winch. A slide bar is provided on the top of the winch and the winch. A set of protective mechanisms is installed on both sides of the slide bar, and a top cover is provided on the top of the slide bar.

[0007] In order to drive the slide bar to rotate, as a production device for continuous stranding and tension synchronization control of flexible cable core wires according to the present invention, preferably, the driving mechanism includes a drive motor, the output end of the drive motor is connected to the connecting plate through a transmission belt, one side of the connecting plate is connected to one side of the first gear, the top of the first gear is meshed with the bottom of the second gear, the top of the second gear is meshed with the bottom of the third gear, and one side of the third gear is connected to one end of the slide bar; The internal movement of the connecting disc and the first gear passes through the guide tube, and the first gear is mounted on the outer wall of one side of the winch via a bearing.

[0008] In order to enable the slide bar to rotate stably between the two end plates, as a production equipment for continuous stranding and tension synchronization control of flexible cable core wires according to the present invention, preferably, one end of the slide bar is integrally connected to one end of the bidirectional screw, and one end of the slide bar and one end of the bidirectional screw are respectively rotatably connected to an end plate through a bearing, and the bottom of the end plate is installed on the outer wall of the top of the strander. A connecting bar is screwed onto the bidirectional screw, and a limiting rod is provided parallel to one side of the bidirectional screw and the slide bar; The two ends of the limiting rod are respectively connected to one side of an end plate, and the limiting rod is movably sleeved on the connecting bar.

[0009] In order to isolate the stranding part of the strander and winch from the outside world, as a production equipment for continuous stranding and tension synchronous control of flexible cable core wires of the present invention, preferably, the protective mechanism includes an elastic winding drum and a transparent film. The top of the elastic winding drum is installed at the bottom of the side rod at the end of the strander away from the bearing seat, and the transparent film is wound inside the elastic winding drum.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: a production equipment for continuous stranding and tension synchronous control of flexible cable core wires, including a frame 1, a tensioner 2 installed on the surface of one end of the frame 1, the tensioner 2 being used to adjust the tension of the flexible cable core wires to ensure uniform tension of the core wires during stranding and to avoid problems such as core wire slack, excessive stretching or uneven stranding.

[0019] A bearing seat 5 is provided on one side of the tensioner 2, and a stranding device 7 is provided on one side of the bearing seat 5. The stranding device 7 is used to realize the continuous stranding operation of the flexible cable core wires, and to strand multiple core wires into flexible cable core wires that meet the specifications.

[0020] A conduit 4 is installed through the interior of the bearing housing 5 and the strander 7. The conduit 4 is used to thread the core wire of the flexible cable and provide guidance for the conveying of the core wire to prevent the core wire from shifting or wearing during the conveying process. A synchronous pulley 3 is installed on the outer wall of the conduit 4 near the tensioner 2. A drive mechanism 6 is installed between the bearing housing 5 and the strander 7. One end of the winch 7 is connected to the bearing on the winch 8. The top of the winch 7 and the winch 8 are provided with a slide bar 9. A set of protective mechanisms 11 are installed on both sides of the slide bar 9. The top of the slide bar 9 is provided with a top cover 10.

[0021] Preferably, the drive mechanism 6 includes a drive motor 61, which is fixedly mounted on the surface of the frame 1 and located between the bearing seat 5 and the winch 7, providing power to the entire drive mechanism 6. The output end of the drive motor 61 is connected to the connecting plate 62 via a transmission belt to realize the transmission of power. One side of the connecting plate 62 is fixedly connected to one side of the first gear 63 to ensure that the connecting plate 62 and the first gear 63 rotate synchronously. The top of the first gear 63 is meshed with the bottom of the second gear 64, and the top of the second gear 64 is meshed with the bottom of the third gear 65. The gear meshing realizes the direction of power and speed adjustment to meet the rotation requirements of the slide rod 9. One side of the third gear 65 is fixedly connected to one end of the slide rod 9 to ensure that the slide rod 9 can rotate synchronously when the third gear 65 rotates. The internal movement of the connecting disc 62 and the first gear 63 passes through the guide tube 4. Bearings are provided between the guide tube 4 and the connecting disc 62 and the first gear 63 to avoid interference between the guide tube 4 and the two, and to ensure that the guide tube 4 can rotate independently and stably. The first gear 63 is mounted on the outer wall of one side of the winch 7 through the bearing, which provides support for the rotation of the first gear 63 and ensures the stability of gear meshing. The drive motor 61 is started, and its output drives the connecting plate 62 to rotate via a transmission belt. The connecting plate 62 drives the first gear 63, which is fixedly connected to it, to rotate synchronously. The first gear 63 drives the second gear 64 to rotate through meshing transmission. The second gear 64 then drives the third gear 65 to rotate through meshing transmission. Since the third gear 65 is fixedly connected to the slide rod 9, its rotation will drive the slide rod 9 to rotate synchronously, thereby providing power for the rotation of the slide rod 9 and the bidirectional screw 91, realizing the linkage action of the subsequent protection mechanism 11. At the same time, the conduit 4 rotates independently under the drive of the synchronous pulley 3, and works with the strander 7 to complete the conveying and stranding of the soft cable core. The gear meshing structure of the drive mechanism 6 can realize the stable transmission of power and speed regulation, ensuring that the rotation speed of the slide rod 9 is matched with the stranding speed of the strander 7, and ensuring the overall coordination of the equipment operation.

[0022] Preferably, one end of the slide rod 9 is integrally connected to one end of the double-acting screw 91, ensuring that the slide rod 9 can drive the double-acting screw 91 to rotate synchronously when it rotates, avoiding power transmission loss between the two. The two ends of the slide rod 9 and the double-acting screw 91 are respectively rotatably connected to an end plate 93 through a bearing. The end plate 93 provides support and limit for the slide rod 9 and the double-acting screw 91, ensuring the stability of the two during rotation and preventing deviation or shaking. The bottom of the end plate 93 is fixedly installed on the outer wall of the top of the winch 7 with bolts, ensuring that the end plate 93 is firmly installed and can stably withstand the force generated when the slide rod 9 and the double-acting screw 91 rotate. A connecting bar 92 is screwed onto the bidirectional screw 91. The outer surface of the bidirectional screw 91 is provided with bidirectional threads. The connecting bar 92 has a threaded hole that matches the bidirectional threads, so that when the bidirectional screw 91 rotates, it can drive the connecting bar 92 to move along the axial direction of the bidirectional screw 91. A limiting rod 94 is provided parallel to one side of the bidirectional screw 91 and the slide bar 9. The limiting rod 94 is used to limit the movement of the connecting bar 92 and prevent the connecting bar 92 from rotating synchronously with the bidirectional screw 91. Both ends of the limiting rod 94 are fixedly connected to one side of an end plate 93 to ensure that the limiting rod 94 is firmly installed. The limiting rod 94 is movably sleeved on the connecting bar 92. The connecting bar 92 has through holes that are compatible with the limiting rod 94, so that the connecting bar 92 can move smoothly along the axial direction of the limiting rod 94, further improving the stability of the connecting bar 92 during movement.

[0023] In practical use, when the drive mechanism 6 drives the slide bar 9 to rotate, the bidirectional screw 91, which is integrally connected to the slide bar 9, rotates synchronously. Since the bidirectional screw 91 is screwed into the connecting bar 92, and the connecting bar 92 is movably sleeved on the limiting rod 94 through a through hole, the limiting rod 94 restricts the rotational freedom of the connecting bar 92. Therefore, when the bidirectional screw 91 rotates, the connecting bar 92 does not rotate with the bidirectional screw 91, but moves linearly along the axial direction of the bidirectional screw 91. By controlling the forward and reverse rotation of the drive motor 61, the following can be achieved: The forward and reverse rotation of the bidirectional screw 91 drives the connecting bar 92 to reciprocate linearly along the bidirectional screw 91. The movement of the connecting bar 92 can drive the pull rod 114 connected to it to move synchronously, providing power for the opening and closing of the transparent film 112 in the protective mechanism 11. The end plates 93 and bearing structures at both ends of the slide bar 9 and the bidirectional screw 91 ensure the stability of their rotation, while the limiting rod 94 ensures the smooth movement of the connecting bar 92, avoiding problems such as jamming and deviation, and ensuring the normal operation of the protective mechanism 11.

[0024] The protective mechanism 11 includes an elastic winding drum 111 and a transparent film 112. The top of the elastic winding drum 111 is fixedly installed at the bottom of the side rod at the end of the strander 7 away from the bearing seat 5 by a bracket to ensure that the elastic winding drum 111 is firmly installed. The transparent film 112 is wound inside the elastic winding drum 111. A return spring is provided inside the elastic winding drum 111, which can automatically retract the transparent film 112 when it is not under tension, so as to realize the automatic reset of the transparent film 112. The transparent film 112 is made of a high-strength, high-transparency flexible material, which can effectively block the stranded wire area without affecting the operator's observation of the equipment operation status. The other end of the transparent film 112 is fixedly connected to one side of the pull rod 114 to ensure that the transparent film 112 can move synchronously when the pull rod 114 moves. The top of the pull rod 114 is fixedly connected to one side of the connecting bar 92 through a crossbar, so that the pull rod 114 can move synchronously when the connecting bar 92 moves, thereby opening and closing the transparent film 112. The bottom of the pull rod 114 is movably inserted into the groove of the guide rail 113. The guide rail 113 guides and limits the movement of the pull rod 114, ensuring that the pull rod 114 moves smoothly along a straight line and preventing the transparent film 112 from shifting or wrinkling. The bottom of the guide rail 113 is fixedly mounted on the surface of the frame 1 with bolts to ensure that the guide rail 113 is firmly installed and can stably withstand the force generated when the pull rod 114 moves. The bottom of the elastic winding drum 111 is fixedly mounted on the surface of the guide rail 113 with a bracket to further improve the installation stability of the elastic winding drum 111 and make the position of the elastic winding drum 111 and the pull rod 114 match to ensure the smoothness of the transparent film 112 when it is wound and pulled open.

[0025] In practical use, when the linkage bar 92 moves away from the elastic take-up drum 111 under the drive of the bidirectional screw 91, the linkage bar 92 drives the pull rod 114 to move synchronously along the slide groove of the guide rail 113 through the crossbar. The pull rod 114 pulls the transparent film 112 out from inside the elastic take-up drum 111. At this time, the return spring inside the elastic take-up drum 111 is compressed, generating a return force. After the transparent film 112 is gradually pulled open, it will accurately cover the stranded area of ​​the strander 7 and the winch 8, thereby effectively preventing workers' hair, clothing, etc. from getting caught in the stranded area when the equipment is running and the flexible cable core stranding is being manufactured, avoiding safety accidents and improving the safety of operators when the equipment is running. When the equipment stops... When the protection is in operation or not required, the control drive motor 61 reverses, driving the bidirectional screw 91 to reverse, causing the connecting bar 92 to move closer to the elastic winding drum 111. The pull rod 114 then resets. At this time, the return spring inside the elastic winding drum 111 releases its elastic force, automatically retracting the transparent film 112 and winding it inside the elastic winding drum 111, preventing the transparent film 112 from being exposed to the outside for a long time and thus extending its service life. The guide rail 113 ensures the smooth movement of the pull rod 114, preventing the transparent film 112 from wrinkling or tearing during the opening or closing process. The double fixing structure of the elastic winding drum 111 ensures its operational stability, ensuring that the protective mechanism 11 works reliably for a long time.

[0026] In addition, the top cover 10 installed on the top of the winch 7 has its two ends wrapped around the top of the transparent film 112. The top cover 10 is made of rigid material, which can effectively block metal shavings, dust and other splashes generated during the production process from falling from the top of the equipment into the winch area, preventing the splashes from affecting the normal operation of the winch 7 and the winch 8, reducing the occurrence of unexpected equipment failures, and further improving the safety of equipment operation. Together with the protective mechanism 11, it forms an all-round protective structure to fully protect the safety of equipment operation and operators.

[0027] Working principle: The drive mechanism 6 is activated, causing the slide bar 9 and the bidirectional screw 91 to rotate between the two end plates 93. When the bidirectional screw 91 rotates, it moves the pull rod 114 to one side. This movement of the pull rod 114 during use allows the transparent film 112 inside the elastic winding drum 111 to be pulled open. Once opened, the transparent film 112 covers the stranded area of ​​the winch 7 and the winding disc 8, preventing workers' hair or clothing from getting caught in the stranded area during manufacturing, thus improving personnel safety during equipment operation. The top of the winch 7 is equipped with a top cover 10, with both ends of the top cover 10 wrapped around the top of the transparent membrane 112. This structure prevents splashes from falling into the winch area from the top of the equipment during use, thereby improving equipment operation safety and reducing unexpected malfunctions.
